At 179 KB, this PDF for the 2SB1495 is one of the larger documents in the set and likely includes graphs alongside rating tables. It sits in the schematic category, yet the plain JIS part number points to a single-component datasheet. In Japanese numbering, 2SB stands for a PNP low-frequency transistor, typical of power and audio circuits. Check pinout, maximum dissipation and safe operating limits here before replacing a failed device, and confirm the package type fits the board footprint.
